Key release highlights

 

Graphics processing unit (GPU) solver optimizations deliver up to 1.5 times faster simulations

The GPU linear solver has undergone extensive development to fully utilize newer and more powerful GPU devices. Significant performance improvements can be observed in both single and multi-GPU simulations with the new default behaviors, with an average of 1.5 times speed-up relative to the previous version observed in a suite of representative test models.

The GPU linear solver has been enhanced to maximize performance on modern GPU hardware. With enhanced default behavior, users can achieve significantly faster simulation runtimes across both single-GPU and multi-GPU configurations. Benchmark testing on a representative set of models shows an average performance improvement of up to 50%, delivering faster insights and improved productivity.

Improved accuracy and speed for fractured reservoir simulations with multiscale

The multiscale sequential fully implicit (SFI) transport solver has been optimized for fractured reservoir simulations, using the embedded discrete fracture model (EDFM), providing both higher solution accuracy and significantly faster runtimes. In tested cases, the enhanced solver delivered performance gains by orders of magnitude, accelerating simulation workflows while maintaining reliable results.

More accurate well simulation for deep geothermal cases

The thermal well model has been enhanced to account for potential energy, improving the accuracy of temperature predictions along the wellbore. This contribution can be particularly significant for deep wells and near-adiabatic systems. This enhancement enables more realistic modeling of temperature predictions along the wellbore, and is especially beneficial for applications such as geothermal reservoirs, where these conditions may be encountered.

Key enhancements

Physics and new energies

  • The relative permeability hysteresis and surface tension miscibility models can now be combined, enabling engineers to account for more complete physics of gas and water injection into reservoirs with complex petrophysics behavior.

  • A functionality was added to allow capping the maximum capillary pressure coming from J-function initialization, ensuring physically realistic results, and more stable simulations.

Usability

  • Simulation well logs (e.g., Repeat formation tester and Production logging tool) can now be output at times specified by the user, enabling easy matching for dates of real or scheduled well events.

  • Surface network reports have been enhanced, adding information to the output print files, and enabling a better understanding of coupled surface-subsurface cases such as IxNetwork.

  • A new workflow example illustrating in-situ leaching of uranium has been added, highlighting essential physics and operational model requirements for critical mineral operations.

  • The EGRID Report and multiscale extensions are now automatically loaded based on their activation in the ixf files, and no longer need to be included in the .afi file, increasing usability for cases which may use them.

Systems

  • The Intel MPI version provided with the installation has been updated to 2021.18.
